There are players who can be written off forever-Ghambir,Sehwag,Harbhajan,Ojha,Zaheer,YusufPathan,IrfanPathan are all good players past their fine days and now start off other lucrative ventures;Must invest in youth going forward as a few failures can form their learning curve and now when India is anyways not doing well in TESTS is the right time.Going back to the above veterans is like NO HOPE situation and only they make hay out of it.
Can't say about one day matches, but test series result is already know unless Virat n Pujara come back to form and they find a good opening pair. Indian team has no bowlers anyway.
Do you think this team has any juice left? Hope there is enough grass left on the surfaces that would kill each test match in three days. It is sick watching Indian test team overseas. They are bad. PERIOD.
